The C11H6TM080L is a current-production ComPacT NSXm moulded-case circuit breaker from Schneider Electric, a 4-pole thermal-magnetic unit rated 80 A at 40 °C with a 70 kA interrupting capacity at 415 V AC (H performance level). It's built to EN/IEC 60947-2, which covers the construction and testing of low-voltage switchgear for industrial distribution panels. The thermal-magnetic trip unit (TM-D) handles overloads via a bimetal strip and short-circuits via a solenoid — no external trip module to fail, no auxiliary power needed for the trip mechanism.
Connection pitch is 35 mm with spreaders, 27 mm without — that's the centre-to-centre distance between phases, so check your busbar or cable-lug spacing before laying out the panel. Terminals are Everlink lugs accepting 2.5 to 95 mm² rigid or stranded aluminium/copper, or 2.5 to 70 mm² flexible copper. The 4-pole unit occupies 12 module pitches of 9 mm each on a DIN-rail-compatible backplate.
Overvoltage category III suits fixed-installation distribution boards.
